Before the trees have fully leafed out this spring, take advantage of the improved visibility to spot birds. The arb is a breeding destination for many species, and serves as temporary way point for a large number of additional migratory species. Look for migrating waterfowl on Lyman Lakes and the Cannon River in late March and April. Spring warblers are abundant in May along the river trail, in the floodplain forest, in Best Woods and near Spring Creek in the Upper Arb
Song Sparrow (Melospiza melodia) This medium-sized sparrow is easily identified by its streaked breast and central breast spot, as well as its characteristic trilled song. The song sparrow is a common Arb resident during the summer; it spends the colder months wintering in Mexico and the southern USA.
